摘要:
Disclosed herein is an apparatus and method for balancing the color of a flashed image using depth estimation. The apparatus includes a depth value measurement unit, a region identification unit, a color impression estimation unit, and a color balancing unit. The depth value measurement unit measures the depth values of the respective regions of an image to be captured using a camera preview image. The region identification unit identifies the regions of the preview image as a region influenced by camera flash or a region not influenced by camera flash using the depth values measured by the depth value measurement unit. The color impression estimation unit estimates the color impression of actual illumination in the region not influenced by camera flash. The color balancing unit corrects the color of the region influenced by camera flash.

Disclosed are peptide derivatives, wherein glutathione-like peptides are connected to benzoic acid derivatives, and a cosmetic composition comprising the same. The peptide derivatives have excellent tyrosinase inhibition and anti-oxidative activities to show excellent skin whitening effect, biocompatibility without skin stimulation, and stability during long-term storage. Therefore, they can be effectively used for a cosmetic composition for skin whitening.

Disclosed herein is an apparatus for enhancing images in consideration of region characteristics. An inverse gamma correction unit releases gamma correction and linearizes each of Red (R), Green (G), and Blue (B) colors. A threshold calculation unit calculates m-1 thresholds in order to divide the brightness of pixels into m regions, and labels each of the pixels as one of the m brightness regions. A block segmentation unit divides an input image into M×N blocks. A block statistics calculation unit determines one of the m brightness regions to which each of the blocks pertains, and labels the block as the corresponding brightness region. A block-based Look-Up Table (LUT) generation unit generates enhancement LUTs for the respective blocks. An image enhancement unit corrects the image using the LUTs for the respective blocks. A gamma correction unit performs gamma correction.

A method and an apparatus for performing handover in a mobile communication network are provided. The method of performing handover in a mobile communication network includes: obtaining a service providing time period and a utility function on a candidate network basis; obtaining a selection function of each of the candidate networks using the utility function and the service providing time period; and selecting a network for handover among the plurality of mobile networks using the selection function. Therefore, in consideration of user satisfaction and a network service quality, utility functions are defined and by selecting a network for handover using the utility functions, a network suitable for a user environment can be effectively selected and thus it is possible to perform handover that has a performance and a cost suitable for user request and that can maximize a quality of a mobile service.
